Examination of the projections with light and ­electron microscopy revealed invaginations of epidermal tissue reminiscent of those characterizing the light organs of adults (Haygood personal communication cited in Baldwin and Johnson, 1995).

These females are adapted for living in deep waters in a nutrient poor environment by minimal energy expenditure, relying much on lethargic drifting as documented in videos taken by unmanned submarines (Moore, 2002; Luck and Pietsch, 2008).

This feeding strategy is particularly well suited for conserving energy, since sit and wait predators on average devote just 2% of their energy intake to swimming activities (Kitchell, 1983).
